We're building the next-generation decentralized prediction market — fast, transparent, and community-driven. We’re re-imagining on-chain speculation with real utility and fun — a platform where users can create, trade, and settle markets on any event with real-time speed and gamified UX.

We’re now looking for a world-class backend and smart-contract developer to take full ownership of the EVM backend architecture and program design — from protocol logic to APIs, data indexing, and live on-chain settlement.


What You’ll Build

  • Core prediction market protocol (smart contracts, liquidity logic, resolution mechanisms).
  • Backend infrastructure for real-time data updates, on-chain/off-chain syncing, and analytics.
  • Secure APIs for frontend & partner integrations.
  • Event-based oracles & automated market creation flows.
  • Staking, settlement, and yield distribution modules.
  • Admin and governance layer for market validation.
  • CI/CD and deployment for testnet → mainnet rollout.


You Should Have

  • 5+ years backend or blockchain engineering experience (Node.js, Go, or Rust).
  • 3+ years of EVM-based smart-contract development (Solidity, Hardhat, Foundry).
  • Deep understanding of DEX/AMM mechanics, liquidity pools, and market resolution logic.
  • Proven experience deploying and managing smart contracts on Base, Polygon, or Ethereum mainnet.
  • Familiarity with event indexing (The Graph, custom indexers, oracles).
  • Experience building secure APIs, WebSockets, caching layers, and on-chain data pipelines.
  • Proficiency in PostgreSQL, Redis, AWS/GCP, and Docker/Kubernetes.
  • Solid grasp of security, gas optimization, multisig flows, and upgradeable contracts.
  • Bonus: prior work on prediction markets, perpetuals, or DeFi protocols.


Nice-to-Haves

  • Experience integrating with Chainlink, Pyth, or UMA oracles.
  • Familiarity with on-chain verification, dispute systems, or governance frameworks (OpenZeppelin).
  • Background in data streaming, Web3 analytics, or real-time trading UIs.
